Yeah you have to buy them from the trainer in that specific city so it would be hard as a human to get orgrimmar teleport lol =p
Just FYI: Normal spells trainers dont teach you teleport spells, you need to find the "portal trainers" they are in capital cities with the other mage trainers but they can be sneaky, might take a few seconds to find them.
